Question

the cost of mathematics book RS 25(3/4 and that of science book 20(1/2 which cost more and by how much ​

Answer 1

Answer:

25 3/4 = 25*4+3/4=103/4

20 1/2 = 20*2+1/2 = 41/2

103/4 - 41/2=103/4 - 82/4=103–82/4=21/4=5 1/4

hence the 1st book costs more than second book by 5rs25paise

(or)

it’s just seeing them in the form of money

1st book cost = 25rs75paise (3/4 of a rupee = 3/4 * 100 = 75paise)

2nd book cost = 20rs50paise (1/2 of a rupee = 1/2 * 100 = 50 paise)

1stbookcost - 2ndbookcost = 5rs25paise

hence the 1st book costs more than second book by 5rs25paise
